This is the only rule that passes:
1. Players may voluntarily change their height. Voluntary height changes may only occur during the offseason. The first voluntary height change is free. Any voluntary height changes after the first one cost 4m. Voluntary height changes must be within the specified height range for each player archetype. Forced height changes due to archetype/position changes are always free and this rule does not apply to them.
(Reason for the this is we now know that height affects CBs and PDs, so it may affect other positions as well. Weight changes are free so height changes should be as well)
